G7 Master Printer
What a G7 Master Printer means to you and your printing needs. Reed & Witting has been verified through a certified G7 Expert auditor, that Reed & Witting understands and is in compliance with ISO 12647-2 print standards and GRACoL specifications using the G7 neutral print density curve methodology. This process has improved our printing accuracy to a high degree. To simplify why this effects you, by using ISO 12647-2 standards and the G7 Master printer certification Reed & Witting can better track colors and correct them faster and with more accuracy than ever before. This control has allowed our press men to focus more on the fine details of your project rather than trying to get the piece in basic specification. This process also bridges the gap that has existed between pre-press and the press for the proofs to match the final print. Having the ability to have a closer visual match between the proofs and the final printed product and also between the printed output from press to press is what sets G7 Master printers apart from the rest of the industry. The control of the pre-press end also allows for color corrections to take place before the job gets on press. Since the ISO standard and G7certification keeps the proof and press to a tight visual match the colors are easier to manipulate in the proofing process, cutting out long press checks and amount of make readies needed for a given job.
Bridging this gap has allowed for better control of the visual appearance and also allows for a more sustainable approach to printing. Matching the proof to the press takes less time and plate makeovers are no longer required. The make readies on the press are also reduced as color is hitting to the specifications on the second pull. This allows Reed & Witting to be able to process your project faster and with fewer make readies than ever before, translating into lower cost due to less time on press and a greener printing method due to less material being needed to print a project.
As it is important to understand all of the elements that Reed & Witting provides we wanted to make sure we go over what exactly ISO 12647-2 and G7 are. ISO 12647-2 is the International Organization of Standardization; the 12647-2 is the worldwide standard for printing, setting a defined printing targets and tolerances for four color process printing. These targets vary according to both substrates and printing methods. The main targets are based on Lab values (L stands for light and â€œaâ€ and â€œbâ€ for color-opponent dimensions) for the primaries and their Tonal Value Increase curves with additional targets for gray balance, over prints and paper color. The purpose for the standards is to help printers achieve the quality that are to benefit both the printer and customer. There is a lot of science behind printing and Reed & Witting is at the forefront of it.
G7 was developed by the IDEAlliance and the GRACoL committee, G7 is named for its gray scale calibration technique and the 7 ISO ink colors it requires. The â€œGâ€ refers to calibrating Gray values, while the â€œ7â€ refers to the seven primary color values: Cyan, Magenta, Yellow, Black, Red, Green and Blue. It describes how to use the principles of digital imaging, spectrophotometry and computer-to-plate technologies to achieve these color matches using quality inks and papers. Basically, G7 is a set of instructions of the methodology for calibrating a press or proofing system based on spectrometry (colorimetric data) for gray balance instead of traditional densitometric (dot gain / TVI) methods. By using gray balance a constant color reproduction can be achieved multiple times. Allowing for reprints to match and printed pieces to be printed in multiple G7 printer locations and have an extremely close visual match that is not possible otherwise.
